Description

Pressure visualization and restoring pressure adjustable motorcycle shock absorber Technical Field The utility model relates to the technical field of motorcycle shock absorbers, in particular to a motorcycle shock absorber with adjustable air pressure visualization and restoring pressure. Background The existing automobile and motorcycle shock absorbers mainly adopt nitrogen auxiliary damping structures, mainly comprise a gas cylinder assembly, a valve system assembly, an adjusting assembly, a main shaft core assembly, a sealing piece and the like, and realize a shock absorption and buffering function by matching internal nitrogen pressure with a damping valve. The conventional shock absorber has the following problems: 1. The nitrogen pressure in the traditional shock absorber cannot be visually monitored, a user cannot judge whether the air pressure is normal or not, if the air pressure leakage (the air pressure approaches to 0) occurs, the air pressure can be found only through disassembly and detection, and the failure of the damping function cannot be timely detected; 2. The traditional external detection structure is easy to leak nitrogen, and impurities such as external muddy water, sand grains and the like are easy to permeate into a sealing surface, so that the sealing effect is damaged, and the service life of the shock absorber is influenced; 3. Damping adjustment is fuzzy, namely the damping adjustment is operated by relying on manual experience, and cannot be accurately set according to quantized air pressure data, so that the damping matching degree is poor under high-speed and low-speed working conditions; 4. The anti-vibration and anti-corrosion performance is deficient, namely, the air pressure detection part is not designed with a buffer structure aiming at high-frequency vibration in the running process of the motorcycle, data display distortion is easy to occur, the surface treatment is not combined with the characteristic optimization of the air pressure part, and the corrosion resistance is difficult to meet the long-term outdoor use requirement; 5. The structural compatibility is poor, the structural suitability of the traditional additional detection component and the gas cylinder of the shock absorber is insufficient, the overall volume and the weight are easy to increase, and the installation and the use flexibility of the shock absorber are affected.
